The key to providing your rabbits with a stimulating day is to vary their surroundings. A great way of doing this is to put toys in their run. These don't have to be bought; you can use things that you already have at home. Rabbits like to hide in things, climb onto different levels and chew so here are some suggestions:
It may seem simple but as with small children the box the toy comes in is often more exciting than the toy itself! It handily provides your rabbit with something to chew on and also something to hide in.
Drainage pipes and cardboard tubes make great toys for rabbits. They whizz through them, hide in them and will even reverse out of them if they meet something coming the other way!
Apple tree branch:
Branches from an apple tree are a safe and natural nibble for your rabbits. Make sure it's an apple tree because some fruit trees such as plum and cherry are poisonous to rabbits.
Avoid giving your rabbit any sharp objects or things that your rabbit could get trapped in.
